I have a BCM-101 Dehumdifier, model DE226Y-GBHB

Until recently it has worked perfectly however now when I turn it on it makes a noise to indicate it's running (like a fridge) but it doesn't collect any moisture & the green light on the top no longer comes on.... does anyone have any suggestions? Dad's taken it apart & can't see anything obviously wrong
